IMPROVEMENT IN SAWING-MACHINES.

Specification forming part of Letters Patent No. 43,7211, dated August2', 1864.

To all whom it muy concern Beit known lthat I, E. TO'IMAN, of Columbus,in the county of Warren and State of Pennsylvania, have invented a newand Improved SaWing-Machine; and I do hereby decare that the following`is a full, ch a", and eX- act description thereof, which will enablethose skilled in the art to make and use the same, reference being hadto the accompanying drawings, making a part of this specification,

in whiclil Figure l is a side sectional View of my in vention, taken inthe line a' x, Fig. 2. `h`ig. 2, a plan or top view of the same.

This invention relates to a new and improved machine for sawing logs andtimber transversely, designed more especially for sawing logs intosuitable lengths for fuel.

A represents what may be termed the base of the machine, constructed inany suitable minner, and having an upright, B, at one end of it, throughwhich a vertical shaft, O, passes, the latter having a crank-wheel, D,on its lower end, to which a pitman, E, is attached, said pitman havinga saw, F, secured to its, outer end. rlhe shaft O has a box, G, placedon itsv upper end above the upright B, the box being allowed to turnfreely on the shaft, and on the top of the box G there is placed ashaft, H, having a bevel-wheel, I, upon it, the latter gearing into abevel-pinion, J, on the shaft C. To the shaft H a shaft, K, is attachedby ai universal joint, a, having a wheel, L, on its outer end, theperiphery of which is provided with spurs b, to prevent slipping. Theouter end of the shaft H has its bearing in the crosspiece c of a frame,M, composed 0f said crosspiece, and two bars dd, which are connected toopposite sides of the box G by a pivot-bolt,

e, to admit of said frame rising and'falling. The horse is attached tothe frame M, and the latter drawn around the shaft C as a center, thebase A having a platform, N, upon it for the `horse and wheel L to passover. rlhe shaft K is rotated by the wheel L and the bevelwheel I,communicating motion to the shaft C through the medium of thebevel-pinion J and thecrank-wheel D and pitman E, communicate areciprocating movement to the saw F. The

' sha-'ft K, it will be seen, is allowed toV rise and fall with theframe M in consequence of being connected to the shaft H by theuniversal joint c. A circular track may be made for the wheel L to runupon, or the earth may simply be graded and pounded to form a hardsurface.

Thus it will be seen that by a very simple mechanism I obtain aneffective sawingmachine, which may be constructed at a small cost,equally so as those which are not provided with any means for applying amotor.

I claim as new and desire to secure by Letters PatentrIhe frame M,attached to a box, G, on a vertical sha-ft, O, and provided with ashaft, K, having a wheel, L, upon it near one end, and connected at itsopposite end by a universal joint, a, to a shaft, H, in connection withthe bevel-gearing I J, placed on the shafts H and C, the crank-wheel Don the lower end of shaft O, the pitman E, and saw F, all arranged tooperate substantially as and for the purpose set forth.,
